Synotrip Performance Optimizations

This project is only for Petrovalex. Nobody else need bid on it. Please deal with the performance related issues as discussed in our email: 2) Cache views and blocks (if possible). 3) Manipulate the images file sizes to reduce their size without loosing quality. AND combine theme images into one image, of which pieces will be used via CSS. (I believe this is called using 'CSS sprites', although I could be wrong about the terminology.) 4) Analyze the css files and delete unused css classes and maybe divide css files into several groups of files and ensure that the css files are loaded only on the pages they are needed. The same goes for javascript files. 5) Go through all the php/html files and remove the dummy code generated by drupal and optimize poorly written html.
